Top critical review
Got it working, but not in the way I expected.

EDIT: Formatting this on the PSP through the USB connection as FAT32 using 3rd-party formatting software seemed to do the trick. I can play games off it now (though I have to make multiple attempts at starting games to get past error 80010013)!
I tried to use this on my PSP-1001 with 2 32GB SanDisk microSD cards. Trying to format it on the PSP resulted in an error message saying "There is no Memory Stick inserted." It could still read files on the card, but it would often become unresponsive for 15 seconds. After putting Pro Updater on the card, it showed up in the XMB, but it wouldn't load. Just a black screen and nothing else. It worked when I ran it off my older 32MB Memory Stick, though. I'm going to return this and see if I can get a better adapter from somewhere else.
